After a part of the side impact force is counteracted by the reinforcing sheet 1, the side impact force is transmitted to the inner sill beam plate 4 through the transverse and longitudinal reinforcing ribs which are vertically arranged. The transverse and longitudinal reinforcing ribs are perpendicular to the reinforcing sheet 1, so that the support is more stable.
Optionally, the thickness of the longitudinal reinforcement 2 and the thickness of the transverse reinforcement 3 are increased or decreased in a stepwise manner in a direction from the rocker outer panel 5 to the rocker inner panel 4.
In this embodiment, two longitudinal reinforcing ribs 2 may be arranged in parallel up and down, a plurality of transverse reinforcing ribs 3 are arranged at intervals along the direction shown by the X axis, and each longitudinal reinforcing rib 2 and each transverse reinforcing rib 3 are connected in a cross manner to form a plurality of continuously connected "well" shaped structures.

The continuous glass fiber reinforced sheet can adjust the performance of parts within a certain range through the density and the number of layers of glass fibers so as to realize required rigidity and strength, and the size and the thickness of the continuous glass fiber reinforced sheet are not changed, so that an injection mold of the automobile threshold reinforcing structure is not required to be changed.
